1. What is indicated by 1 through 3 in the illustration of the DNA molecule?

2. If a molecule of DNA were found to contain 33% adenine, could you calculate the expected amounts of the other bases? What would they be?

Adenine pairs with thymine in a 1:1 basis. Therefore, there would be 33% thymine.

3. Which would be harder to break, the adenine-thymine base pair or the guanine-cytosine base pair. Explain your answer.

The guanine-cytosine base pair would be hardest to break, as these two bases have three hydrogen bonds holding them together. Adenine-thymine base pairs are only joined by two hydrogen bonds.

4. List the parent strand of DNA then list its complimentary DNA strand.

5. List the parent strand of DNA and then list its complimentary mRNA strand.

6. List the sequence of codons for each, list its corresponding amino acid.

7. What is the amino acid sequence for the mRNA strand.
